SAAMI pressure testing protocol uses a conformal piezoelectric quartz transducer for pressure testing of centerfire pistol and revolver, centerfire rifle, and rimfire cartridges. The primary source of the conformal transducers is the US company PCB Piezotronics. The SAAMI pressure testing protocol uses test barrels that have a hole located in ...
The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. In 2009 an additional three calibers were tested and in 2010 and 2011 more calibers were added. Also in 2011 testing was carried out to study the "cylinder gap effect" on the velocity of ammunition shot from ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
For this, a highly accurate and indisputable protocol has been defined by NATO experts using a system of reference cartridges. [1] [3] [4] The civilian organisations C.I.P. and SAAMI use less comprehensive test procedures than NATO, but NATO test centres have the advantage that only a few chamberings are in military use.
The table below shows how the rounds compare. Note that reloading data for 160-grain (10 g) bullets for some of the cartridges is not available. This round was designed with an elastomer tip, so that the .308 designed would be safe for the tubular magazine of lever action rifles.
The .45-60 Winchester / 11.6x48mmR is a centerfire rifle cartridge intended for 19th-century big-game hunting. [4] Nomenclature of the era indicated the .45-60 cartridge contained a 0.45-inch (11.43 mm) diameter bullet with 60 grains (3.89 g) of black powder.
A popular 7 mm hunting caliber bullet is actually .283 in diameter (7.2 mm), but wildcat cartridges using this caliber bullet in a 5.56 x 45 case have so far not been successful. There is an existing and well-developed use of hunting-rifle bullets in the .277 caliber (6.8 mm), introduced by Winchester as the 270 in 1925.
